SELF-LIMITED (FAMILIAL) INFANTILE EPILEPSY (SeLIE)

Mandatory seizures

Focal seizures with behavioural arrest, autonomic features (e.g. cyanosis), impaired awareness, automatisms, head/eye version, and clonic movements may occur. These may alternate sides from seizure to seizure. Seizures are brief (<3 minutes) but frequent e.g. 5-10 per day over 1-3 days at onset. One third of patients present with a single isolated seizure 10-15 days before frequent seizures commence. Longer seizures (3-6 minutes in duration) can occur but are rare. Seizures remit but may recur after 1-3 months in a third of patients.

May have

Focal to bilateral tonic-clonic seizures

Exclusionary

Epileptic spasms

Myoclonic seizures

CAUTION Prolonged focal or hemiclonic seizures (>10 minutes) are not seen in this syndrome right arrow consider Dravet syndrome.
